Calendar-first email · powered by KnowDrive

Your week is the inbox.
Mail docks to its moment.

Chrono lays every Google account — Gmail and Workspace — on one board built from time itself. Each email lands on the day it belongs to, wired to the meeting it came from, across every calendar you run.

Sign in with Google. No card, no forms — the board assembles itself from your week.

The problem

Email pretends time doesn't exist.

The inbox is a pile. Your calendar is a plan. Every message is secretly about a when — and you pay the tax of joining the two by hand, all day, in two different apps.

01

The pile hides the plan

A hundred unread rows say nothing about your Thursday. The mail that matters is the mail attached to the meetings, deadlines, and days you already committed to.

02

Accounts fragment the week

Work, personal, the side project — three inboxes, three calendars, one life. Switching contexts is where the afternoon goes.

03

History evaporates

The thread that settled the launch date exists — somewhere, in some account, under some subject line. Search that can't remember isn't search.

The board

Every account. Every calendar. One board built from time.

Chrono renders your week as a living 3D board. Fold it flat for the classic grid; stack it to see every calendar on its own plane. Mail counts sit under each day, and reply wires literally hang between the mail that arrived and the moment you answered it.

Mail docks to events

Invites, updates, and the emails a meeting generated dock to the event itself. Open the moment, and its mail is already there.

Keyboard-first, always

Everything reachable without the mouse — archive advances to the next email, RSVP is one key, search is a slash away.

"No mail has docked to this event. An honest empty panel beats a full one that lies."

The corpus

Ask your mail anything. It remembers.

Chrono ingests your email and events into a KnowDrive corpus at full fidelity — the complete original messages, byte for byte. Local matches appear the instant you type; semantic recall follows from everything you've ever filed.

local

Instant on every keystroke

Subjects, people, places, and event titles from your synced accounts answer at typing speed.

.eml

Full-fidelity memory

The corpus stores the real thing — headers, bodies, attachments — so what you find is what was actually sent.

Answers land in time

An event hit flies the board to that event's week and calendar. An email hit opens the whole conversation. Escape returns you to the results.
